I first only saw that you were missing migrate_set_error().
migrate_get_current() is .... more interesting.
The problem is that migration.c has lots of things that depend of qemu
and we can't use that in qtest.
This is one disection toh help fix it, but I can't see a trivial way to
get current_migration() working as needed. Really what we should have
is a way to have vmstate store its own error, and only set
migrate_set_error() at callers time, but that don't seem completely
obvious how to do it.
Later, Juan.

Subject: [PATCH] migration: Create common.c
We can (yet) add migration.c to migration_files because it brings too
many dependencies to the tests.
This file is a place where to move things that are also needed for
tests.
